Substitutions
Oats blended with water and enzyme-treated to release their starches, producing a creamy, faintly sweet plant milk that froths well.
What it does in a recipe: A neutral, creamy plant liquid with enough body to stand in for milk almost anywhere. Pick the swap that covers that job — the ratios below are written so you can act on them without doing any arithmetic.
Quick answer
Soy milk
1 cup oat milk = 1 cup unsweetened soy milkAll substitutes, best first
1 cup oat milk = 1 cup unsweetened soy milkThe closest plant milk in body, and better in baking because its protein content does the structural work oats cannot.
Trade-offBeanier in flavour; less naturally sweet.
Allergen checkSoy is a top allergen. Check the label if allergies are in play.
1 cup oat milk = 1 cup whole milkSimilar body and sweetness, with more fat and protein.
Allergen checkNot a swap where dairy avoidance is the point. Listed for the cook who simply ran out of oat milk.
1 cup oat milk = 1 cup unsweetened cashew milkAmong the creamiest nut milks, so it comes closest to oat milk's mouthfeel.
Allergen checkCashews are a tree nut. If oat milk was chosen specifically to be nut-free, this is the wrong direction — use soy or rice milk instead.
Oats are naturally free of gluten but are routinely harvested and milled alongside wheat, so only oat milk labelled certified gluten-free is safe for a coeliac.

Cooking around an allergy? Diet tags here describe the ingredient itself, not any particular brand. Processed products change formulation without notice and shared production lines are common, so read the label on everything you use. A severe allergy is a medical matter — confirm with the manufacturer or your clinician rather than relying on a substitution chart.
